Hello K3 owners.
I need to replace U1 on the KIO3 board.
In my K3 sn: 218x the part nr is: SN75C1406 G4.
Is there any other SN75C1406 can be replaced with the ''old one''.
Thanks in advance :-)

Ah, lightning. Whoever performs an analysis of the KIO3 failure mode after
being struck by lightning might have what's necessary for a very lucrative
business.
Actually, I'm surprised that the board hasn't already been reverse engineered
in China, enabling an aftermarket for KIO3 replacements.
Had the same thing a few years ago. I plugged the PP into the K3 only it was
offset a bit. Nanacged to get the cable Red on the K3 Black. Smelled smoke (P3
cable insulation) and blew L1 on the RS232 circuit.

Working with Rob at Elecraft Service, I removed and checked the KIO3
Digital I/F board and found L1 blown. L2, L3, R12, and R13 are all
good. L1 is on the ground lead from the sub-D9 connector, pin 5 to
ground in the K3. Definitely blown as there is a carbon smudge next
to L1. I installed a
I had exactly that same problem, Ed, and I also first thought it was the
USB/RS232 cable (which it wasn't). I also do not need the direct USB
connectivity, or the associated internal sound card. Luckily, I was able
to buy replacement boards from someone who had done the upgrade to the
KIO3B
Oh yes. And the only way out is to upgrade the whole system. Or look for used
items here.

It seems at least possible that the polyphonic audio bleat is being
produced by feedback somehow occurring between LIN IN and LIN OUT on
the KIO3. Two possibilities - either the sound card has failed in
this peculiar way, or there is some setting, either in my WIN 10
computer's sound settings
I am trying to diagnose a problem with my K3/KIO3 which surfaced during

I have problems with my KIO3 main board. I wonder if there is someone
who have upgraded to KIO3B and have KIO3 board collecting dust.
If so I want to buy it. Please send an e-mail with your price.

Dr. Jim,
I really don't know the answer to your question, but I suspect a fair
value would be between 1/2 and 2/3 of the original price for the KIO3
option.
I do not recall what that price was, but perhaps someone with an older
price sheet will chime in.

I have one spare as well.
But I have to say I'm having great fun with my KIO3B. I even bought a
$349 HP laptop and installed Ubuntu to run WSJT-X and fldigi. It's
pretty fun.

I'm writing a Windows program for the K3. It connects at 38400 only. In trying
to figure out what's wrong, I set my P3 and K3 to 9600 and used the K3 Utility.
It will not connect.
If I set the K3 to 38400 and leave the P3 at 9600, the utility connects, but
reports it's connected at 9600.
